NAME
stmfSetLuProp, stmfGetLuProp - set or get a logical unit property
SYNOPSIS

cc [ flag... ] file... -lstmf [ library... ]
#include <libstmf.h>

int stmfSetLuProp(luResource hdl, uint32_t prop, const char *propVal);

int stmfGetLuProp(luResource hdl, uint32_t prop, char *propVal,
 size_t *propLen);
PARAMETERS
hdl

A logical unit resource previously allocated by stmfCreateLuResource(3STMF) or stmfGetLuResource(3STMF).

prop

A property type value. See DESCRIPTION for valid values.

propVal

A property value.

propLen

The length of the specified property value. If propLen was of an insufficient size to hold the returned property value, propLen will contain the required size of the buffer and STMF_ERROR_INVALID_ARG will be returned.

DESCRIPTION

These functions set or get property values. All property values are expressed in human-readable form. Boolean properties are expressed in case insensitive form of "true" or "false". Properties that are represented by ASCII hexadecimal contain no leading characters to indicate a base hexadecimal representation (that is, no leading "0x"). The prop argument can be one of the following values: STMF_LU_PROP_ALIAS

Up to 255 characters representing a user defined name for the device. Default: Set to file name of backing store.

STMF_LU_PROP_BLOCK_SIZE

Numeric value for block size in bytes in 2^n. Default: 512

STMF_LU_PROP_COMPANY_ID

Organizational Unique Identifier. 6 hexadecimal ASCII characters representing the IEEE OUI company id assignment. This will be used to generate the device identifier (GUID). Default: 00144F

STMF_LU_PROP_DATA_FILENAME

Character value representing the file name of the backing store device. Default: None

STMF_LU_PROP_GUID

ASCII hexadecimal string of 32 characters representing the unique identifier for the device. This must be of valid 32 hexadecimal ASCII characters representing a valid NAA Registered Extended Identifier. Default: Set by framework to a generated value.

STMF_LU_PROP_META_FILENAME

Metadata file name. When specified, will be used to hold the SCSI metadata for the logical unit. Default: None. If this value is not specified, the value specified in STMF_LU_PROP_DATA_FILENAME will be used.

STMF_LU_PROP_MGMT_URL

Up to 1024 characters representing Management Network Address URLs. More than one URL can be passed using space delimited URLs.

STMF_LU_PROP_PID

Up to 16 characters of product identification that will be reflected in the Standard INQUIRY data returned for the device. Default: sSet to COMSTAR.

STMF_LU_PROP_PRODUCT_REV

Up to 4 characters of revision information that will be reflected in the Standard INQUIRY data returned for the device. Default: Set to 1.0.

STMF_LU_PROP_SERIAL_NUM

Serial Number. Specifies the SCSI Vital Product Data Serial Number (page 80h). It is a character value up to 252 bytes in length. Default: None

STMF_LU_PROP_SIZE

Numeric value w/optional suffix, e.g. 100G, 1T, to specify unit of size. Default: Size of the device specified in the STMF_LU_PROP_DATA_FILENAME property value.

STMF_LU_PROP_VID

8 characters of vendor identification per SCSI SPC-3 and will be reflected in the Standard INQUIRY data returned for the device. Default: Set to SUN.

STMF_LU_PROP_WRITE_CACHE_DISABLE

Write back cache disable. When specified as "true" or "false", specifies write back cache disable behavior. Default: Writeback cache setting of the backing store device specified by STMF_LU_PROP_DATA_FILENAME.

STMF_LU_PROP_WRITE_PROTECT

Write protect bit. When specified as "true" or "false", specifies whether the device behaves as a write protected device. Default: "false"

RETURN VALUES

The following values are returned: STMF_STATUS_SUCCESS

The API call was successful.

STMF_ERROR_INVALID_ARG

Either prop or propVal is unrecognized.

STMF_ERROR_INVALID_PROPSIZE

The size of propVal is invalid.

STMF_ERROR_NO_PROP

The value of prop is unknown for this resource type.
